To all fw tom t may concern:

Be it known that l, JOHN SOMMER, a citizen of the UnitedStates, residing at Peoria, in the county ot Peoria. and State ot illinois, have invented new and useful Improvements in Bale-Tie Machines, of which the following is a specification. Y

This invention has reference to bale-tie machines, and it has `for its principal Object to provide an endless movable element to which is attached a plurality of twisting mechanisms, each arranged during its travel to grip a feed-wire, sever the front end portion of an unformed bale-tie from the rear end portion of a formed bale-tie, draw the feed-wire through the machine, bend the end of the wire into a loop, twist the looped end to the body of the wire, and discharge the completed bale-tie into a trough or other receiving means. Y

The invention'has for a further object to' move the endless movable element in a horil Zontal plane; the twisting` mechanisms operating during their travel down one side of the machine, and back the other, to form the bale-ties from continuous feed-wires, sever the formed bale-ties from the stock and discharge the same onto some suitable receiving means. i

Each twisting mechanism comprehends a carriage in which is rotatably mounted a twisting' element; wire gripping and severing means; means for removing the looped and twisted end oit' the bale-tie from the twisting;` element; means to discharge the tie after the twisting o} )eration, and means foroperating the several mechanisms in timed relation with respect `to each other, whereby the operation of forming bale-ties is continuous. That the invention may be more fully understood reference is had to the accompanying drawings forming, 'a part of the description, in which Fignre 1 is a fgreatly reduced side elevation of 'a bale-tie machine (partly broken away) embodying my invention;

Fia'. 15 is an elevation, in Vcross-section` as the same would appear if taken on the line 15-.15 of Fig. 10;

Fig. 16'is an elevation, in cross-section, as the same would appear if taken on the line 1.6-16 of Fig'. 10;

Fig. 17 is. an elevation of one of the intermittent bevel gear wheels. the same would appear on the line 17-17 Fig. 10;

Fig. 18 is an elevation of the companion gear wheel., to that shown in Fig. 17, and as the same would appear on the line 18-18 The main .supporting frame for the machine'comprises the pair of spaced Vlongitudinally disposed angle iron bars 1. These bar-s are connected to headers 2 secured respectively to ther standards 3 and braces 4, which, in turn'are connected to therfloor rails 5.

At; or near the left hand end of the machine, looking at Figs. 1 and 2, and supportedby bars 1 is a bearing support composed of the upper and lower castings 7 and 8 bolted together and to said bars 1. At or near the right hand end of the machine, looking at Figs. 1 and 2, and supported by bars, 1 is a bearing support 9 composed of the upper and lower castings-10 and 11.

Connecting ,the castings 7 and 10 of the supports 6 and 9, respectively, are a pair of spaced rails 12 and 13 which have corresponding rounded ends 14. Connecting the castings 8 and 11 of the said supports 6 and 9, respectively, are a pair ofspaced rails 15 and 18 which have corresponding rounded ends 17. The rails 15 are spaced below and in the same vertical plane with the rails 12, and the rails 16 are spaced below and inthe same vertical plane with the rails 13.

The opposite straight stretches of the rails 12, and the opposite rounded ends thereof are duplicates; this is also true of the opposite straight stretches of the rails 13, and the 'opposite rounded ends'thereof, as very plainly seen in the plan View Fig. 6, looking up from the under side of the bed.y For instance, the under side of the rounded ends 14 of the rails 13 are provided with the rather long spiral racks 18, andv along the under side of the straight portions of said rails 13 between the rounded ends, and approximatelyimidway therebetween are also provided the rather longspiral racks 19, which are connected with the racks 18 by the connecting tooth-webs 20. The underside of the opposite straight stretches of the rails 12, near one end, are provided with the oppositely arranged short spiral racks 21 and 22, and at a suitable point on the underside of the rounded ends of the rails 12 are provided short spiral racks 23, the teeth of which are arranged to correspond to the teeth of the racks 21, and said racks 21, 22 and 23 are connected with each other by t-he connecting tooth-webs. 24.

On the rail '16,* see Fig. 1, there is provided an elongated cam-lug 24. This lug, as will be seen, is located approximately at the juncture where the straight Vstretch of the rail merges into the rounded end, and

Vthis arrangement is duplicated at the 0pposite diagonal corner lof the machine. On the rail 15, see Figs. 1 and 5, there 1s provided -a comparatively short cam-lug 25.

. This lug, like lug 24, is located approximately at the juncture .where the straight stretch of the rail merges into the rounded end, and this arrangement is also duplicated at the opposite diagonal corner of the machine.

In the bearing support 6 is journaled the short vertical shaft 2,6, on the lower end of which is carried a driving-'sprocket wheel 27, and on the upper end of which is carried the bevel gear wheel 28, meshing kwith a bevel gear pinon 29 on one end of a horizontally disposed counter-shaft 30, journaled at its outer end in the bearing support 6 and at its inner end in a bearing support 31. In the bearing support 9 is Vjournaled the short vertical shaft 32, on the'lower end of which vis carried a driven sprocketwheel, or idler 33. `Engagmg the sprocket wheels 27 and 33 and traveling therebetween is the sprocket chain 34. Y

Power may be imparted to the counter shaft 30, as follows: 35 is a motor suitably supported on the baseof the machine, and on the motorshaft is a pulley wheel 36, driving a belt 37, operating aV driving pulley wheel 38 on a driving shaft 39, which also carries a pulley wheel 40 operating a belt 41 which in turn operates the drum 42 of a clutchV on the counter-shaft 30. The friction driving part 43 of this clutch is splined on the shaft 30, whereas the drum 42 rotates loosely on said shaft, and said driving part `43 has a groo-ved sleeve 44 to which may be connected any lever operating means (not shown) which maybe convenient an desir-- ableV to enable the operator to control the operation of the machine. 'Y The motor 35 may be connected with'a source of current supply and controlled in any suitable manner. 'Y Y Thus far 1 have described the supporting means for the operating parts; driving mechanism, and endless movable element to which the carriages, to be described, are connected and by means of which the carriages and operating means thereon are caused to traverse the machineV bed and manufacture the bale-ties. 1 will now describe the carriages and their mode of operation, it beingl .The carriage is designated 45 andv comprises the matching cast sections 46 and 47 the inside matchingpfaces of the rails 12v and 13, and on the lower ends of said 'spindlesare carried rollers 53 which roll against the inside matching faces of therails 15 and 16, see F igs.y 14, 15,- and 16. To the lower end of the spindle 50 is connected the chain 34, see Figs. l1 and 13. f

54 and 55 designate coacting wire gripping jaws, see Figs. 10 to 13 and 16. These jaws are pivoted on a common pivot pin 56 and the operative position of the jaw 54 is yieldingly maintained by the spring 57. The jaw 55 is normally out of operative position and is moved to operative position by means of a roller 58 carried thereby which moves over the cam-lug 24. W hen the jaws 54 and 55 are inoperative position they engage a bale-tie wire to feed `it through the machine. The jaw 54 has an extension 59 with which coperates the combined cutting' suitably formed sinuous groove 69 arrangedV in the` end of a busher bar 70 Vhaving the Jforked end 71. aid bar is guided in its longitudinal movement by means of a' pin 72, which it carries, and which moves back and forth in a slot 73 arranged longitudinally in a covering plate 74, also provided with a forked end 75. The crotch of the forked end 71, in the pusher bar, is normally in axial alinement with a slotted twistingmember 76, on the body of which is arranged a slotted segment gear wheel 77.

The segment gear wheel 66 slides in mesh with the tooth-web 24 on the rail 12, until the wheel 66 coincides with either of the racks 21, 22 or 23 when rotation is imparted to said gear wheel and parts associated therel with. The same is true ofthe segment gear wheel 77 on the twister member, which slides in mesh with the tooth-web 20 on the rail 13, until the wheel 77 coincides with either of the racks 18 or 19 when rotation is imparted to said gear wheel and parts associated therewith. i

To the inner end of the twisting member 76 is eccentrically connected an elongated twisting stem 78 which has the hooked end 79. The cutting portion of the end 60 of member 61 coacts with the end of the twisting member 76 when severing the bale-tiewire in two, see Fig. 11, as will be further explained.`

To remove the looped and twisted end of a bale-tie from the hooked end 79 of twisting stem 78, I provide the bell-crank-shaped member 8O fulcrumed at 81, the short arm portion of which carries a roller 82 adapted to roll over the cam-lugs 25 for operating said member. A spring 83 returns the member to the position seen in Fig. 16, after each operation.

During the time when the segment gear wheel 77 is traveling with the carriagey 45, between the racks 18 and 19, the tooth-web 20 on the rail 13V enters the slot 84 and holds the gear wheel against rotation. This gear wheel rotates always in one direction. This is not true of thegear wheel 66 which rotates in one direction, when its teeth mesh withthe racks 21 and 23,` and in a reverse direction when its teeth mesh with the yrack 22, and the tooth-web`24 entering a tooth in said segment wheel 66 holds thev gear wheel against rotation until it coincideswith the racks 21, 22 and 23. i

Reference to Figs; 1, 2 and 5`discloses that bale-tie-.wires A are fed down the opposite sides of the machines, in opposite directions, being drawn by the carriages 45 from suitable reels (not shown) and through the straightening devices 85. The idea being, as

stated in the preamble, tomanufacture or produce bale-ties as the carriages traversefthe opposite sides oi the machine. Eachsucceeding carriage picking up the bale-tie-- wire A immediately upon the completion oi" a tie by the preceding carriage, whenv the completed tie is severed. from the bale-'tiewire stock and discharged onto or into .some suitable receiving` means. j

In operation, describing the action of oneY carriage, all being the same, and referring toh Figs. 1, 2, 5 and 6 as general iigures to illustrate such operation, thecarriage as it comes toward you around the right hand end of the machine will present the jaws 54 and 55 in an open position, as seen in Fig.4 16, to permit the bale-tie-wire stock A to' enter between said jaws. The roller 58 on the jaw 55 will roll over the cam lug 24 which will force the jaw 55 to. grip the' wire AA between it and the jaw 54 and draw the wire through the machine.

The gear wheel 66 is ,rotated asit is brought into coincidence with the rack 22 which will operate bevel gear wheels 634 64 to rotate the member 61 from the position seen in Fig. 11, to the position seeny in Fig. 13, and during such movement the end ofthe bale-tie-wire-stock is looped over the hooked end 79 oi the stem 78, as atB, and the end caught between the gripping end of the member 61 and thejaw 55. This gripping operation occurs about the sam-e time the roller t58 leaves the cam vlug 24', which permits the jaw 55 to drop by action of gravity to an inoperative position. The movement of the member 61 from theposition shown in Fig. 11 to the position shown in Fig. 13 will sever the `rear end of a formed bale-tie from the stock, after the Y initial operation of drawing the stock A into the machine, and during the successive operations, as the carriages succeed each other in their movement through the ma-` chine.

When the segment gear wheel 7 7 coincides with the rack 19 the twisting. member 76 is caused to rotate and it in turnrotates the stem 78 twisting the looped end Bkwith the body ofthe wireA, as at C, see I*`ig.r 19. After the twisting operaticn, and when the gear 'wheel 66 coincides with the rack 22, the bevel gear wheels68 and 6a are partially rotated returning the memberrtl to a position approximately midway between the positions shown inv Figs. 11 and 18, about which time the roller 82 on the bellcrank-arm V80 Vrides on the cam lug 25 which will swing the long end of arm 80 downwaidly and the same engaging with the twisted end of the bale tie, will force it oli or" the hooked end 79 of stem 7 8. TheV hooked endof said'stem havingstopped in aV position pointing downwardly and out- Wardly. When the gear wheel 66 is brought coincident with'the rack 23 the member 61 is caused to be moved the remainder or the distance to position it, as seen in Fig.` 11.

I ,The rack 18, engaged by the gearV wheel 77 66 will be rotated by vImmediately upon the severing of the formed tie from the stock, the pusher bar 70 is operated, whereby the plain end of the tie is ejected from the twister 76 simultaneously with the ejecting of the formed end of the tie from the hoolred end 'of the stem'78.

The operation of the pusher bar from the.

gear-wheel 66,- Fig. la, it is believed is understood and does not require further ei;-V

planation.

It is obvious that various changes may be made in the machine without departing from the spirit and scope or the invention, and I do not want to be limited to the precise details except as I may be limited in the appended claims.
